java - JDO - Determine entities affected by transaction commit -

-

मैं एक जावा वेब प्रोजेक्ट को एक JDO आधारित दृढ़ता से एक साथ रखने के शुरुआती चरणों में हूं

यदि मैं अपने HTTPServlet और commit या रोलबैक में एक लेनदेन शुरू करता हूँ आउटपुट स्ट्रीम की प्रतिक्रिया लिखने से पहले सर्वोलेट, क्या वस्तुओं की सूची प्राप्त करने का कोई तरीका है (या सिर्फ आईडी) जो कि कमिट द्वारा बदला गया था? यदि हां, तो प्रदर्शन क्या होगा?

अपडेट:

मैंने अभी तक ऐसा नहीं किया है, लेकिन ऐसा लगता है कि एक InstanceLifecycleListener को जोड़ने से स्थिरता प्रबंधक चाल करता है।

एक इंस्टेंस लाइफसाइकिल लिस्टनर जोड़ना से स्थिरता प्रबंधक अच्छी तरह से अब तक काम कर रहा है। एकमात्र पकड़ा यह नहीं था कि क्लासेस [] पैरामीटर को addInstanceLifecycleListener में छोड़ दें। इसके बजाय अगर आप सभी परिवर्तनों को सुनना चाहते हैं, तो स्पष्ट रूप से null पास करें।

I am working through an advanced search query where users select the checkbox based on multiple criteria. I am starting because I am hoping that I will know whether I am on the right path. I know that the query is quite messy Edit: I realized that there are two questions to be needed, so I have strictly modified a question question table data tables ss_users user_id FIRST_NAME LAST_NAME admin_level user_approved 1 Nick Jones 0 1 2 Johnny Rocket 0 1 table ss_user_profile_status user_id photo_uploaded 1 1 2 1 table ss_user_photos selected user_id file name photo_id 1 1 photo_1 .jpg 1 2 2 photo_2.jpg 0 3 2 photo_2.jpg 1 table ss_general user_id city state zip neighborhood 1 Baltimore maryland 00125 hamsterdam 2 Lekland My 11542 treemont table ss_languages ​​user_id French German Italian Spanish 1 0 1 0 1 2 0 1 1 Table ss_experience Waldorf Kumon homeschooling user_id 1 0 1 0 2 0 0 1 My current The result is that all users, which should not be the case: ...

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
